• enough phenol

  • By the time the plot was discontinued, it had succeeded in diverting enough phenol, according to Albert, to make about 4.5 million pounds of explosives. (wikipedia.org)
  • The public pressure soon forced Schweitzer and Edison to end the phenol deal, with the embarrassed Edison subsequently sending his excess phenol to the U.S. military, but by that time the deal had netted the plotters over two million dollars and there was already enough phenol to keep Bayer's aspirin plant running.

  • compound
  • It is a measure of the bactericidal activity of a chemical compound in relation to phenol. (wikipedia.org)
  • To calculate phenol coefficient, the concentration of phenol at which the compound kills the test organism in 10 minutes, but not in 5 minutes, is divided by the concentration of the test compound that kills the organism under the same conditions (or, probably more common, dividing the dilution factor at which the tested substance shows activity by the dilution factor at which phenol shows comparable activity). (wikipedia.org)
  • excess
  • Edison's excess phenol seemed destined for American trinitrophenol production, which would be used to support the British. (wikipedia.org)
  • Schweitzer, with money funneled from Germany through Albert, set up a contract for a front company called the Chemical Exchange Association to buy all of Edison's excess phenol. (wikipedia.org)

  • Substance
  • When listed numerically, the figure expressing the disinfecting power of a substance by relating it to the disinfecting power of phenol may be a function of the standardized test performed. (wikipedia.org)
  • water
  • In ordinary language it may be called a solution of water in phenol . (dictionary.com)
  • The second is that phenol has a density of 1.07 g/cm3, which is higher than the density of water (1.00 g/cm3). (wikipedia.org)
  • High levels of bromine can convert phenol red to bromophenol red (dibromophenolsulfonephthalein, whose lowered pKa results in an indicator with a range shifted in the acidic direction - water at pH 6.8 will appear to test at 7.5). (wikipedia.org)
  • Being thermosets, hydroxymethyl phenols will crosslink on heating to around 120 °C to form methylene and methyl ether bridges through the elimination of water molecules. (wikipedia.org)
  • clinical
  • Auramine phenol stain is a stain used in clinical microbiology and histology to identify tuberculosis mycobacteria. (wikipedia.org)
  • tissue
  • Phenol exerts a marked corrosive action on any tissue of contact when ingested, inhaled or after skin exposure. (inchem.org)
  • Since the color of phenol red can interfere with some spectrophotometric and fluorescent assays, many types of tissue culture media are also available without phenol red. (wikipedia.org)
  • composition
  • Phenol-Explorer is a comprehensive database on natural phenols and polyphenols including food composition, food processing, and polyphenol metabolites in human and experimental animals. (wikipedia.org)
  • known
  • Phenol red (also known as phenolsulfonphthalein or PSP) is a pH indicator frequently used in cell biology laboratories. (wikipedia.org)
  • solution
  • For phenol to be effective the pH of the solution must vary according to what is being extracted. (wikipedia.org)
  • Phenol red solution is administered intravenously, the urine produced is collected. (wikipedia.org)
  • Phenol red, sometimes labelled with a different name, such as "Guardex Solution #2", is used as a pH indicator in home swimming pool test kits. (wikipedia.org)
  • species

  • The reactive species is the phenoxide anion (C6H5O−) formed by deprotonation of phenol. (wikipedia.org)
  • careful
  • Schweitzer sold the remainder of the phenol at a considerable profit, being careful to distribute it to only non-war-related industries. (wikipedia.org)
  • involves
  • The initial reaction in all cases involves the formation of a hydroxymethyl phenol: HOC6H5 + CH2O → HOC6H4CH2OH The hydroxymethyl group is capable of reacting with either another free ortho or para site, or with another hydroxymethyl group. (wikipedia.org)
  • Group
  • The simplest phenol, consisting of a benzene ring attached to a hydroxyl group (OH). (dictionary.com)
  • In several sources, the structure of phenol red is shown with the sulfur atom being part of a cyclic group, similar to the structure of phenolphthalein. (wikipedia.org)
  • test
  • there never was any phenol in the test tube. (dictionary.com)
  • The Chick-Martin test was then widely used until replaced by more suitable tests not reliant on phenol and reflecting the conditions in which modern disinfectants are used. (wikipedia.org)
  • Phenol red was used in the phenolsulfonphthalein test to estimate the overall blood flow through the kidney and is now obsolete. (wikipedia.org)
